Although constructions are getting diverse, larger in size, and higher-storied, we witness that CM technologies are not coping with such a growing trend. In particular, CM, one of vulnerable areas, shall continue to be given priority hereafter. The research has been conducted with a strong focus on total design and supervision offices already specializing in CM projects, in order to prepare for the future activated CM markets. Authors have sought to find mistakes in the process of being in control of CM works and create measures to boost CM through case-study, documentary research, and interviews with experts. It excludes theoretical research, as many data are already accumulated domestic and abroad.

Due to a waste of energy in korea, about 525,000 which are 75 percent of total buildings are at least 15 years old buildings that need remodeling. There are two current remodeling systems. One is a remodeling system to reduce a waste of resources from the reconstruction. The other is a green-remodeling system aimed to energy savings and reducing environmental costs. This study is to analyze quantitatively these current systems with respect to the cost-benefit caused by the life cycle and suggests the political and institutional implications through the interpretation of the results. For a quantitative analysis, we analyzed reducing maintenance costs and rent benefits with simulation by using opportunity costs, construction costs, plan costs and supervision costs as expense variables and using the reduced floor area ratio, institutional incentives, energy, water resources and certified emission reduction(CER) as benefit variables. As a result of the empirical study, the green-modeling was more beneficial in the field of environment such as the energy savings, however, the final benefits of remodeling which has no green building certification costs but more floor area ratio incentives were more economical. The green-remodeling system focused on reducing environmental costs and energy savings needs a equatable institutional incentive system.
